The bandwidth used by Hangouts is adaptive and will vary to provide the best experience for the given conditions of the participants’ network. Here is a guide for the minimum and maximum bandwidth requirements and expectations:

Minimum bandwidth required:

Outbound from the participant: 300 kbps

Inbound to the participant: 300 kbps

Ideal bandwidth for the best experience:

Outbound from the participant: 2.6 mbps

Inbound to the participant: 2.6 mbps

With group video calls of more than 2 people you can expect bandwidth usage in ideal situations to be:
